Application filed October 25, 1920. Serial No. 419,281.

T 0 all whom it may con cern Be it known that I, CARL YAEGER, a citizen of the United States of America, resicling at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Brush Making Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to brush making machines and more particularl to brush making machines wherein the bristles or the like are fed into engagement with a brush block through a suitable nozzle.

Machines of this type as heretofore constructed have employed a nozzle with a longitudinal slot in communication with the ristle passage to allow disengagement of each tuft of bristles from the nozzle by the backward movement of the brush block after anchorage of such tuft therein. Because of this structural feature such machines have heretofore been limited in their use to the production of brushes having the bristles bent at substantially a mid point so as to double the same in forming the tufts. It has not been feasible in the use of such machines to fold the bristles adjacent an end thereof for the reason that the short end portions could protrude through said slot while being fed through the nozzle and consequently allow an escape of the bristles from proper engagement with the feeding means. Certain kinds of bristles used in brush making are not, however, adapted to be doubled to form the tufts of the brushes, because of a lack of uniformit between the ends of the bristles. Such brlstles may be coarse and stocky at one end and relatively fine at the other. It has been necessary, heretofore, in using such nonuniform stock to resort to comparatively slow hand operations because of location of the fold adjacent one end of the bristles.

It is the object of the present invention to associate with the slotted nozzle of a brush making machine, a bristle retaining device that will permit folding of the bristles uite close to an extremity thereof without danger of the tuft falling apart as it is fed through the nozzle.

In the accompanying drawings: Figure 1 is a front view of the tuft gathfeeding mechanism, in which position the bristles are being forced into the brush back. I

Figures 3, 4, 5 and 6 are detail views showing various positions assumed by the pivotal dog employed in the invention to establish a lost motion drive between two adjacent reciprocating parts;

Figure 7 is a cross section taken on line 77 of Figure 2;

Figure 8 is a side view of the nozzle of the machine with the bristle retainer in raised position, a tuft of bristles being shown in their initial position of engagement with said nozzle.

In these views, reference character 1 designates a portion of the frame of a brush making machine which portion supports the tuft gathering and bristle feeding mechanism. 2 is a slide which is vertically reciprocatory in the member l. 3 is a. needle which depends from the slide 2, being clamped to the lower end of said slide by the plate 3. The needle 3 registers with the central passage 4 of the nozzle 5 and is adapted to force tufts of bristles, one of which is indicated at 6 in Figure 8, through said nozzle. The nozzle is clamped by a plate 7 to a projection 8 upon the frame 1 and depends from said projection as is clearly shown in the drawings. 9 indicates the oscillatory tuft gatherer which is pivoted as indicated at 10 upon an arm 11 projectin in front of the slide 2 from one side of t e head 1. The member 9 comprises a se ental plate 10 and the curved finger 11 ownwardly projecting from said plate and notched as indicated at 12. Said tuft gatherer is adapted to rock from the position shown in igure 1 to that disclosed in Figure 2. In the former position the notch 12 is in communication with the feed box 13 from which the notch will be charged with bristles suflicient to form the desired tuft. By movement of the tuft of the nozzle into its bristle gatherer to the position shown in Figure 2, the char e of bristles in the notch 12 will be locate above the no a le 5 to be" forced through said nozzle upon lowering of the needle 3. The seginntal portion 10 of the tuft gatherer retains the bris: tles in the feed box during swinging of said element. As the needle 3 is lowered to force the bristles 6 through the nozzle 5 the tuft gatherer returns to its initial position. The parts above briefly described are not n'ovelyand a more detailed description and illustration "of the same may? be had it desired in United States Patents M55957 of March 5; E90? and 846,583 of March 12, 1907. i The present invention consists in associating with the nozzle 5 a'bristle retainer coinprisin a pair of reciprocating fingers 13 engaging the front and "back of said n'ozz-le so as to extend across l'llBVilItlGSll slot 14 which opens from the front and rear faces feeding passage; The'front and rear races of itllfi nozzle are formed parallel asinclicated at 15 50 as to be snugly engaged by the fingers 13 in the various positions of the latter. Also the head or topp'ortion 1611f the nozzle is vertically slotted at 17 forwardly and rearwardlv of the depending nozzle portion to adapt the finigers 13 to enter said slot at the upper liinit of their stroke as shown in Figure 8. The fingers 13 are secured to the lower extremity ofa cylindrical stem 18, the upper endfot which is threaded as indicated at 18 to engage the lower end of the rectangular lunger member 19. Said member has a-re uced upper portion engaging a bearing 20 carried by the frame 1 adja-eent to the top thereof and the ste n-1 L54 is provided 'witha bearing in the p'roj ec- A To establish a lost motion drive connec' tion from the 'slicle to the plunger member 19, a'dog 2P1 is pirated at 22; upon a lug: 23 carried by the pin ng-er saicldog beinglocated intermediate said plun er and the frame 1. A' lug" Qs'cairried by the upper portion of the slide 2 is adapted to engage the upper end of the dog' 21 for actuatiri a downward travel of the plunger member during a rtioirof the downward stroke (if'said shde and 'a lug fl l is adapted to similarly engage the lower: end "the (log %1'du-ring a i ortion 0:! tlle upward stroke of the slide. crew heads 25; stationary upon the frame; 1,- adjaieerlit one-edgel-thereof, are

engageaibl withbbvel ed faces-Qtrbfthe dog 1 to trip said dog out of engagement with the lugs Q'ifi the desired positions of the plunger t9.

Goasidin'ing new the "operation of the above desirribed ihvention it: is to b'e understood 'first'tha-t the bristle retainer CT-omprising the fingers 13 must be actuated downin a p it e the bristles, into the bores oi the brush back.

Thus in Figure 2 there is shown at 27, a brush back into which the needle is prej'ected. It is necessary to immediately return the bristle retainer to the upper portion of the nozzle after anchorage of a tuft of bristles in a brush back soils to leave the lower portion of the slot 14 unobstructed to permit the disengagement of thetuft from the nozzle through said slot.

It is not feasible however to shift the retainer 13' upwardly to the upper limit of the stroke of t heneedle 3 since the latter is required to rise some distance above the nozzle to 'engagea staple to be formed from a wire 27 which is advanced by means (not shown) into the staple forming chamber 29. These requirements are metby the lost mo tion connection between the slide 2 and plunger 19 which has been describcd. In otherwords, when movement of the slide 2 has brought a staple into engagement with a tuft oi bristles above the nozzle 5 and is about to feed said tuit and staple into the nozzle, the uppermost lug 24 engages the upper dog 2i as shown in Figure 3, and downward travel of the bristle retainer is initiated in unison with the downward travel of the bristle. is the retainer 13 approaches the lower end of the nozzle 5 as shown in Figure 2. the beveleclface 26 at the lower end of the dog 21 engages the lowermost screw head 25 effecting a tripping of said dog to disengage the same from the lug: 2% thus leaving the retainer 13 stationar} during the balance of the downward travel of the needle 3. When the slideQ, needle 3"are again raised the retainer 1 3 remains stationary until the lower lug 24* engages the lower end of the dog 2i, and the upward travel of the retainer effected through such.

screw head 25 so that the final portion of the upward stroke of the slide occurs independently of the retainer l3 and plun gel: 19

It has been found that'through employment of the described bristle retainer in 5 association with theslotted nozzle are brush making machine'it isegpossible to use brisile stock only very slightly longer than the tufts to be formed without any undesirable resulting looseness in the bristles or falling apart of the tuft. as it is fed through the nozzle. i v 1..
